This player feels more solid, less cheaply built than the other players in the Sx70 series.
The key controls on the S770 are placed in a different location on the player than the other players in the series.
It has long, thin pushbuttons along the top-front of the boxlike player that actually appear, at least for me, to work better than the S570 I had also, with its piano-style keyboard controls, when had I had both placed in front of me, side by side.
Needless to say, the better, more solid look and feel of the BDP-S770 model, combined with the same features as the S570, then add the lighted remote and included 3D movie, is worth the price, especially when it is on sale for the same amount as the S570 at regular pricing.
I took the S570 back, keeping the S770 and would ask anyone else to do the same.
